Application iled November 6,

To all whom it may concern:

Be it known that I, PATRICK FLEMING, a citizen of the United States, residing at New Haven, in the county of New Havenand State of Connecticut, have inventeda certain new and useful Improvement inashllasteners, of which the following is a specification.

-My improved fastener is of that class in which the sashes may be engaged together in a condition which holds the window partially opera/so that both sashes may be raised to-` `gether so as to present the ventilation aper ture at the bottom, or both can belowered to getherso as to present the ventilation apertnrcat the top, or'both may beset in an interniediate position so as to divide the ventilation-aperture. A vM` invention'comprises4 provisions wher-ef by the part bolted on one sash partly einn braces vthe part bolted onA the other sash, 4so as to guide the partshas they slide one upon another in the first part of the opening and the last part off the closing movement, combinedwith means whereby the fastener may be adjusted to engage automatically when the sashes are brought into the closed position, or to avoidfsneh engagement at will. lt also allows .the parts to be firmly held in the engaged position, so that the catch cannot be disengaged until the holding means shown as a flanged screw is relaxed. The sashes may be each approximately balanced by sashweightsin the ordinary manner. y

The accompanying drawings form a part of this specification andrepresentY what I consider the bestmeans of ',"carrying out the invention. l l V `Figure 1 is a faoe'yiewpof' a window pro- .vided with this inventlon. Figs. 2 and 3 represent portions on a larger scale. Fig. 2 is a lperspemtivc viewfand Fig. 8a Vvert-ical sections#v All the igures. show the `window yin thev tightly-closed condition, but they indicate plainly the provisions for setting it open `to live different degrees. y y p Similar letters of reference indicate corre spending parts in all the figures where they appear. a f

parts not particularly represented, may be of any ordinary or suitable construction. l) is a plate screwed on the lower rail oi' the upper sash A. It supports a keeper D of approximately semieylindrical section, having a, series of recesses d in its plane face, adapted to receive a bolt or dog at different levels, as may become expedient, and to ein' gage it strongly.

E is a casing screwed on the top rail of the 6o lower sash B, and having arms E $2-, which partially embrace the keeper D', and serve to insure the proper relation of the parts D and lt when the bolt is engaged. This casing E also contains a transverse way with a trans- 6 5 versac slot in its top. The way receives a beveled endedbolt G, into which is tapped a milled headed screw H, which latter is inserted through the slot and traverses the slot as the bolt G, which may be termed also a' 7o "catchf is moved forward and backward by a force imparted by any means. 'lhe under face of the head H is adapted to presenta fair bearing on the upper face of the part E adjacent to the slot, when it becomes necessary to hold the bolt iir'nily in the engaged or disengaged position. y l is a spiral spring inclosed in a suitable recess. lt exerts a force'tending to throw the bevel-ended bolt G into engagement. ThisfSc bolt is adapted to engage in any one of the recesses d to which it may be presented. It will" be understood that the bolt isthrnst outward by the spring l, and engages inthe lowernio'st or in any other ofthe recesses d, aceordingas" the sash A is slightly elevated. To raisethe lower sash the bolt G must be withdrawn against the tension of` the spring I. This is easily eieeted by any person on the interior of the room, by grasping the head H of the 9o `screw-ond drawing the-bolt back ,thereby,-thescrew serving simply as a knob to eect this end. L

f l vVlhenever the lower sash A is raised so that the bolt G is carried above the keeper D', it 95` I ycan be moved farther upward to any required i y l entent, and may bevlowered again without obl strnetion; VrWhen the sash is' lowered sofar 'relatively to 4the other, the nppersash, as to :'o parte and ther.window-frentey and Qli1 gagement, the arms lli El on the part E partially embrace the upright portion D on the part 1,) and insure the correct relation, andas the lbwer sash is moved downward the bevelended bolt G, which with its spring I behind it constitutes a spring-catch, is brought suecessively into coincidence with the se\v eral recesses d, and engages with each successively,

until it the movement is continued sui'licientlyl t'ar the window is tightly closed and the springatch or bolt ti -is engaged .in the lowermost ot the recesses d, as shown.

lt will be understood that il' the catch is left engaged in one oi' the notches d. above the lowermost the sash lli can bedepressed far- ,tlierby a gentle force, thebevel end of the bolt receiving the contact in such manner as to .loi'c ,\tl.1cbolt back, and it will promptly inove out again under the inlluence ol the spring.

.lly turning the screw ll by means of its milled head. Il', so much friction. can be applied to the bolt that itis tightly locked in position, and is incapable o'i` being moved out ward or inward. lf this is done while the bolt is out, and engaging with either of the recesses 1., ii holds the window locked in that position. ll a l'orce is i'irst applied to draw the bolt (.ir back against the tension of the'spring I, and

vthen when it is i'ully back the screw is turned so as to tighten .its hold, it will under those conditions lock the bolt. in the unfastened or ineffective position. \`\'hcn 'my fastener is thus adjusted7 the window may be rasedand lowered inthe ordmary-manner: This conf 3 5 ldition maybe induced temporarily in certain windows which may require to be opened oiten at certain times.

'lhe engagement ofthe part 1)' by the arms lll 'E2 insures that the sashes shall be exactly in line, and that the parts Dand E shall be in close contact when the sashcs are in position `for being fastened. ol' operation in engaging and disengaging even if the sashes have through agev and shrinkage or other fault become loose in other places. This .is also an advantage when the sashes are closed in c'old weather in insuring that the joint shall be close between the upper and lower sashes.

While the details of construction shown in the drawings arc the ones I prefer, they are subject to modifications which would not depart `from the spirit of the invention, and. are intended to be included by the claims. The

This Oivcs certa-int length of the part D, which iterm a keeper and which receives and engages the bolt G at dilierent height-s, may be greater or less than shown. The upper end Oi the keeper may be less beveled than shown.

Parts of the invention can be used without the whole. I can realize some oi the advantages by the use of other forms oi' head to the screw 1I or by using a: simple knob properly attached in place of the screw. Tn. such ease l lose the capacity of fastening the bolt.

Instead oi' placing the .fastening in the midwidth oi the window, as shown, it may be placed at either side. '.l`wo may be used, one on 'each side of a wide window.

I claim as my inventionl. In a window fastener a self-acting spring catch on one sash in combination with a keeper on the other sash, such keeper having a number ofA recesses at different elevations so as to allow the window to be fastened in a slightly opened condition and to allow both sashes to be raised and lowered together to present the opening for ventilation at the top or bottom at will; and with the arms E, E2, on one part partially embracing the upright keeper D on the other part so as to insure 1 i the correct relation of the parts when the catch is engaged, all substantially as herein specified.

2. In a window fastener a sell acting spring catch on one sash in combination with akeeper on the other sash having a' number of vreemseisat different elevations so as to allow the window` tribe fastened in a variablyopen condition and to allow both sashes to be raised and lowered together to present the variable opening for ventilation at the top or bottom at will and with the arms E' 2 on one sash partially embracing an upright guide on the other sash so as to insure the correct relation of the parts horizont-ally and with the fastening screw 1I arranged to hold the catch firmly in either the locked or unlockedgcondition at will or to leave the catch free .to be shifted as required all substantially as herein shown and described.

In testimony that I claim the inyention IOO above set forth I affix my signature in pres-
